Abstract: PURPOSE:To realize quick charging without causing deterioration of battery by providing a discharge circuit and a charge/discharge control section, discharging a battery having unknown residual charge automatically upto the final voltage, and then charging through a constant power supply upto 150% capacity. CONSTITUTION:Four 1.2V unit batteries are connected in series where each battery is 100% charged with l000mAh, l500mAh to exhibit final voltage of 1VX4=4V. At first, a battery 10 having unknown residual charge is connected with the connector 9 of a charger and then a charge/discharge switching control section 4 is switched to connect the battery 10 with a discharge circuit 5 in order to discharge the battery 10. When the control section 4 detects that the battery has discharged upto the final voltage, the battery 10 is connected with a constant current control section 3 and a timer circuit 6 for controlling the charging time is actuated. The timer circuit 6 measures the time (1.5 hours) required for charging a capacity of 1500mAh and the control section 4 stops charging operation upon elapse of 1.5 hours and makes switching to trickle charging operation.

Inventor: SHIBATA HITOSHI
IPC: G01K7/22
Filed: 1995-06-28
Abstract: PURPOSE: To enhance the sealing performance between aN opening part of a metal case and the thick part of a resin body being fitted into the opening part. CONSTITUTION: A connector housing 9 has a double structure of first and second molded parts 9a, 9b and the thick part of connector housing comprises a combination of parts 91a, 92a. At the time of molding the parts 9a, 9b, shrinkage at each part 91a, 91b is suppressed as compared with conventional thick part of single layer structure. Since the shrinkage is also suppressed at a groove part 94b made in the part 91b, the gap between the groove part 94b and an O-ring 10 is reduced thus enhancing the sealing performance between the connector housing 9 and the sensor case 1.

Title: Device for driving objective lens
Inventor: TAKAHASHI NAOMASA
IPC: G11B7/09
Filed: 1987-06-30
Abstract: PURPOSE:To reduce the access time by moving a movable part along the axial direction of a supporting shaft at focus control and driving the moving part around the supporting shaft at tracking control so as to prevent an objective lens from being tilted at the focus control. CONSTITUTION:In forming the image of a laser beam onto a disk face for the write/read to an optical disk, the objective lens driving device is moved by a linear motor 66 to apply coarse access based on a slot on the disk and a scale 70. When out of focus of a beam spot or the positional deviation of a track due to a warp of the optical disk or its deflection is detected, the objective lens driving mechanism makes access accurately to the objective lens to compensate the deviation. The out of focus is corrected by energizing a focus coil 24 to move the movable part 12 with a coil 24 wound thereto in the axial direction through the action of the magnetic field of a magnet 45. Moreover, the positional deviation of the track is corrected by energizing a track coil 26 so as to drive the movable part 12 around a shaft 28 against the elastic force of regulating members 54, 56.

Title: Polyimide/polypropylene laminate film capacitor
Inventor: ISHIZUKA HIROSHI
IPC: C08G73/10
Filed: 1996-06-03
Abstract: PROBLEM TO BE SOLVED: To shield the heat produced from an Al foil and hence prevent polypropylene from being deteriorated owing to the heat, by providing a polyimide film between the Al foil and a polypropylene film. SOLUTION: An all film capacitor comprises repetition of an Al foil 1, a polyimide film 4, a plurality of sheets of polypropylene films 2..., a polyimide film 4, the Al foil 1.... Since there are required two positive and negative electrodes, two times repetition of the same structure provides one unit. More specifically, the one unit comprises layers of an Al foil/a polyimide film/m sheets of polypropylene films/a polyimide film/an Al foil/a polyimide film/m sheets of polypropylene films/a polyimide film. Polyimide is difficult to define a melting point, etc., but it is chemically stable up to 260 deg.C. Since produced heat is interrupted by the polyimide, the polypropylene is prevented from being heated.

Filed: 1995-06-29
Abstract: PURPOSE: To provide a semiconductor device of LOC structure which shows a favorable condition of bonding between inner leads and bonding wires. CONSTITUTION: Polyimide coating 7 and a thermoplastic adhesive layer 8 are applied to the top of a semiconductor chip 1 in this order. The chip 1 is bonded to the underside of inner leads 3 through the thermoplastic adhesive layer 8. In a thus obtained semiconductor device of LOC structure, an organic component from a thermosetting adhesive layer is prevented from sticking to the surface of inner leads before a wire bonding cycle unlike prior art semiconductor devices of LOC structure, which use lead frames formed by sticking a polyimide tape with a thermosetting adhesive layer to metal material for lead frame, and punching the polyimide tape and metal material in an inner lead pattern.  Moreover, in a semiconductor device of LOC structure obtained by the above- mentioned method, burrs or residues resulting from the thermosetting adhesive layer will not stick to the inner lead surface during the punching of inner leads, which leads to a favorable condition of bonding.
